Does anyone know what Guangzhou Xingshi Machinery Co., Ltd. drew in the interview?

You can refer to this, it should be about the same.

Interview procedure of mechanical draftsman

Our company recruits a group of mechanical draftsmen, and I am responsible for the examination of operating skills. I have the following experience:

Many of them are fresh graduates with poor basic knowledge at school. Many people don't even know the size of the drawing. The thick lines, their expression methods, projection relations, proportions and drawing methods are all a mess. Today's students don't know what they have been doing in school for four years.

I have stipulated the following general interview procedures:

I took out an A2 drawing, asked the interviewer to tell me the drawing number, then told me the drawing size, then asked him to find out the proportion of the drawing, how to define the proportion, and then explained the material and weight of the surface parts in the drawing. Hehe, after a turn, there is nothing to say at all.

It's almost enough to have a look, and then test the drawing ability. Let them compare this picture A2 once. A very simple picture with a taper and slope in the middle is almost troublesome.

I admire college students very much and have no prejudice against them, because they are of high quality after all. But the design talent of mechanical drawing is on the one hand, and meticulous is on the other. Imagine how a person who needs to check the basic knowledge can improve the efficiency of design and drawing, and how a person who can't even remember the basic knowledge can rest assured that he can do a job. Recently, there have been several quality failures in the design department of our unit, all of which are caused by the carelessness of the draftsman.

When drawing a base map or blueprint, A3 is sometimes regarded as A2, and the word is as big as a bull's-eye. Sometimes, when A 1 is changed into A2 or A3, the old engineer has to look at it with a magnifying glass. On another occasion, a 30 steel ball was marked as 120 because of improper adjustment of printing scale. Think about it, there are thousands of steel balls in this batch. I'm afraid the buyer will just order it. Fortunately, I took another look.

At school, the teacher's first class was to talk about a line on the map, with tens of millions of gold. I don't know if you have heard of it.

I hope you can lay a good foundation when you study.
